Specification of Letters Patent.

Patented J an. 9, 1912.

Application filed June 21, 1910, Serial No. 568,232.

To all whom it may concern.

Be it known that I, RoYnnN O. CoUcI-I, a citizen of the United States,residing at Charleston, in the county of Kanawha and State of WestVirginia, have invented certain new and useful Improvements inTrolley-Hangers, of which the following 1s a specification. V

The present invention relates to hangers for trolley wires and has forits purpose to provide a device of that character having means wherebythe wire engaging members are secured to the wire through a means whichsimultaneously secures the wire engaging members to their own supportingmeans; and the arrangement of these parts is such that they may beeasily separated for the removal and insertion of the wire.

A further object of the invention is to provide wire engaging elementshaving means adapting them to fit on any standard hanger to which endthe same are provided with neck portions having threaded sections andwhich, when united, provide effective means for securing the wireengaging elements to a supporting bolt.

The invention further contemplates the construction of a hanger of theabove type, which is particularly adapted to catenary work.

The invention is shown in its preferred and modified structures in theaccompanying drawings, wherein,

Figure l is a side elevation of a hanger embodying my invention; Fig. 2is a vertical central section of the same; Fig. 3 is an end view of ahanger, partly in section and partly in elevation, showing an adapterring for any standard hanger.

1 is a malleable iron or stamped'steel shell provided with a boss 2 onits top tapped to fit standard bolts, the tap terminating in an undercutgroove 3 in which the head of a bolt may be seated. Instead of the boss,the shell can be made for span wire suspension or with a fiat oval base,whereby it may be secured to a mine roof or timbers by means of lagscrews. The lower edge of the shell is provided with a series of damping fingers 4.

5 is a porcelain, glass or other suitable insulator which is pressedinto the shell and held firmly therein by pressing down over it thefingers 4 of the shell. The porcelain is provided with the water-shed 6.

7 is a bolt, the head of which is seated in a recess 8 formed in the topof the POIOQ-f lain insulator, and 9 is insulating material secured'insaid recess above the head of the bolt. This bolt extends through thein-f;

lower ends to clamp a conductor wire havmg the cross section of thefigure 8. These clamps have a swell 14 about midway their length, onwhich are formed seats 15 adapt- 'ed to receive respectively the head ofthe bolt 16 and the nut 17. The upper ends of the clampingjaws 12 and 13are flat as at 18 to adapt them to fit snugly against the lower face ofthe .porcelain insulator 5, while' the under faces 19 are formed on abevel corresponding to the bevel of the upper face of the ring 11.

The jaws l2 and 13 are fitted on each side of the conductor wire andaround the bolt 7, whereupon the bolt 16 is passed through the jaws andthe jaws are drawn together by means of the nut 17 The angle of thebevel face 19 on the ring 11 and the angle 10 on the upper end of thejaws being the same, the jaws slide on said ring 11 and are forced inthe space between the ring 11 and the lower face of the porcelain orother insulating substance 5 with the action of a wedge, so that intightening or clamping the jaws on the trolley wire by screwing up thenut on the bolt 16, the bevel ring 11 causes the jaws to seat firmlybetween it and the insulator 5 and likewise pulls down on the bolt 7, sothat all the parts of the hanger and clamp are firmly locked inposition, preventing all wear and jar due to loose parts.

From the above, it will be seen that a hanger constructed according tomy invention is simple in construction, cheap to manufacture has greatheat resisting qualities, and has a maximum strength. The low height ofthe hanger and clamp makes it especially valuable in mining where thereare low veins. In addition to these features,

the present invention is particularly adapted for the purpose specifiedby reason of the absence of the usual intricate joints on suchstructures, which are subject to rust or corrosion; and the means forassembling the wire engaging elements disclosed herein afford perfectalinement of the trolley wire at all times since from the very mannerin 1. In a trolley wire hanger, the combination of the shell andinsulating block secured in said shell, and a bolt secured in saidinsulating block and depending therefrom, of a wedging ring secured onsaid bolt and conductor wire clamping jaws, a bevel face on said jaws toengage with the wedging ring between the ring and block, and means todraw the jaws together to force the jaws against the insulating block,whereby to secure the several parts in firm relation to each other.

2. In a trolley wire hanger, the combination with a bolt, insulatingmaterial secured around said bolt, said bolt depending below theinsulating material, of a ring secured on said bolt and-having an uppercam face and jaws having cam faces on the upper ends of said jaws,whereby when the jaws are clamped together the cam face on said ringforces the ends of the jaws up against the insulating material, therebybinding the several parts in firm relation to each other.

3. In a trolley wire hanger, the combination with a shell, an insulatingblock secured in said shell, and a bolt secured in said shell anddepending therefrom, of a ring secured on said bolt and having an uppercam face,

conductor wire clamping jaws, the upper ends of which are provided withcam faces constructed to engage the cam face of said ring, and means toclamp said jaws together.

The foregoing specification signed at Micco, Florida, this 17th day of June, 1910.
